Class BassLayout

java.lang.Object
  bass.visualisation.layout.BassLayout

public class BassLayout
extends java.lang.Object

BassLayout actually get the right positions for all spheres(band) in the targetbands friendlist and if depth=2 for the friends of the friends as well =). In addition it calculates the directionvector of each edge that connects two bands as well.

calculatePositionsBandnetwork

public static void calculatePositionsBandnetwork(BassNodeList[] nodesToCalc,
                                                 BassEdgeList[] edgesToCalc,
                                                 java.lang.String startBand,
                                                 int depth,
                                                 boolean friendsConn,
                                                 boolean edgeConn)

It calls the calcPosition method

Parameters:

nodesToCalc - Array with all BassNodeList's

edgesToCalc - Array with all BassEdgeList's

startBand - The id of the target band

depth - the hierarchielevel ( 1 or 2 )

friendsConn - should the friends show their connections (edges) to other friends of the friendslist of the targetband?

edgeConn - Should the edges between the mainband and all it's friends be visible?

                                  boolean friendsConn,
                                  boolean edgeConn,
                                  int depth)

Parameters:

nodesToCalc - Array with all BassNodeList's

edgesToCalc - Array with all BassEdgeList's

startBand - The id of the target band

depth - the hierarchielevel ( 1 or 2 )

friendsConn - should the friends show their connections (edges) to other friends of the friendslist of the targetband?

edgeConn - Should the edges between the mainband and all it's friends be visible?

calcPositionsDepth2

private static void calcPositionsDepth2(BassNodeList[] nodesToCalcArray,
                                        BassEdgeList[] edgesToCalc,
                                        java.lang.String startBand,
                                        boolean edgeConn)
